CLEARING A BLOCKAGE
A blockage can be caused by big bones, metal objects or other hard objects that can get stuck in the
propellers or in the in-conveyor itself.
ALWAYS USE PROTECTIVE GLOVES WHEN WORKING WITH BIG HANNA COMPOSTER OR
WHEN HANDLING THE MACHINE AND/OR THE COMPOST.
3.8.1
ALARM INFEED – IN-CONVEYOR HAS AUTOMATICALLY REVERSED 2 TIMES BUT IS STILL
UNABLE TO RUN ALARM INFEED
Follow the instructions on the screen:
Inspection of the in-conveyor is needed. Problem can be caused by food
waste material getting stuck in the in-conveyor. Clean the infeed
hopper and the in-conveyor. If necessary run the in-conveyor in reverse
and thereby loosen any material that is stuck inside the pipe leading to
the cylinder. Once the blockage has been cleared the infeed can be
used again without resetting any fuse/inverter.
Note that this ALARM needs to be acknowledged in the ALARM list in order to turn off the Alarm
Indicator which is visible in the left hand upper corner on all screens.
Use the ALARM button to go to alarm log menu.
From this alarm screen, it is possible to navigate to the
‘manual run infeed’ screen pressing the symbol with
the infeed and two arrows on the alarm screens.
Use the back and forward arrow trying to loosen the
blockage in the inconveyor.
Note that the lid of the infeed hopper must be closed – the infeed auger does not work otherwise!
The function of the in-conveyor motor trying to reverse two
times if something gets stuck before sending an alarm can be
adjusted in ‘tools’ menu.
The frequency inverter setting is set using this menu. These
parameters may need adjusting to the quality of the food waste
material if the inverter gives this alarm when nothing is actually
blocking the in-conveyor or only gives this alarm when the
blockage is too tight.
If the alarm says ‘ALARM – Infeed motor – fuse tripped’ see further information on alarms in Chapter
10 Troubleshooting – Machinery – Alarms.
If the infeed hopper, propellers and in-conveyor have been cleared and the alarm comes back
contact service personnel.
